Specification of Letters Patent.

"Patented June 24, 1913.

To all whom it may concern:

Be it known that I, IGNAC BASINSKI, a subject of the Emperor ofAustria-Hungary,

residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Compressed-Air Motors,of which the following is a specification, reference being hadtherewhere easy access cannot behad to a source ofgelfl triqityiorpthersour eof po er? A-further ofoject Of 'thlS invention is a} providea'motor wherein a series of, air cylinders are employed for imparting acon tinuous rotar movement to a drive shaft.

With the a ve and other objects'in view, the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein Figure 1 is a plan ofa motor in accordance with this invention, Fig; 2 is a side elevation ofthe same, Fig. 3 is a longitudinal sectional view of a portion ofthemotor, Fig. 4 is a cross sectional view ofthe same, and Fig; 5' is adetail sectional view of one of the air cylinders.

The reference numeral 1 denotes a foundation frame, rectangular in planand provided with corner pieces 2 and 3 connected by longitudinalgirders 4.

Mounted upon the foundation frame 1, between the posts 3, is a largemetallic cylinder or tank 5" that has an air inlet pipe 6 communicatingwith a source of air Suppl provided with a globe valve 7 of the ordinaryand well known type. An air pump can be connected to the pipe 6 to pumpair into the tank 5 and compress the same therein, the pressure of airwithin the tank 5 being ascertained by a pressure gage 8 connected tothe tank 5, adjacent to the top thereof, said gage being of aconventional form.

Arranged upon the foundation frame 1 are transverse bed plates 9 and 10and mounted upon the former are curved frames 11 having the upper endsthereof connected to the girders 4 and intermediate the ends providedwith guides 12. Mounted upon the bed plate 9, beneath the guides 12, arecylinders 13 that have the lower ends thereof connected by pipes 14 tothe tank 5, said pipes being in communication with the tank adjacent tothe upper end thereof. The pipes 14 have valves 15 of a conventionalform that permit of the sup 1y of air to the cylinders. 13 being shut 05or regulated. One of the cylinders 13 is illustrated in detail in Fig. 5of the drawings. The cylinder has a piston rod-16, a piston 17, acylindrical valve casing 18, a valve 19 slidably mounted in said casingand connected to the ,piston rod 16 by a stem 20. The valve 19 closes aport 21 in the lower end of the cylinder-13 during an upstroke of thepiston rod 16, and the port 21 is uncovered during a down stroke of thepiston rod to allow air to exhaust from thecylinder. Located upon thepipes 14 are check valves 22 of a conventional form that shut off thesupply of' air to the cylinders 13 during a down stroke of the pistonrod 16.

The piston rods 16 are provided with pitmen 23 and 24. The pitmen 23 arepivot- ;ally' connected to cranks 25 of. ashaft 26,

journaled in bearings 27,- carried by the girders 4. The pitinen 24 areconnected to eccentrics 28 carried by the shaft 27,- adjacent'to thecranks 25.' The shaft 26, intermediate the ends thereof, has a sprocketwheel-29, and the ends of the shaft are provide'd with balance wheels3(" Mounted upon the bed plate 10 are vertical posts 31 having brackets32 supporting .a transverse auxiliary tank or cylinder 33.

This tank or cylinder is connected to the main tank or cylinder 5 by apipe 34, said pipe having a globe valve 35and a check valve 36, both ofwhich are of a conventional form, the latter being of that type that canbe set either in an active position or in an inactive position.

Mounted upon the bed plate 10 are cylinders 37 and 38 similar to thecylinders 13. The cylinders 37 are connected to the auxiliary tank 33 bypipes 39 and the cylinders 38 by pipes 40, said pipes having checkvalves 41 similar to the valves 36. V

The cylinders 37 and 38 have piston rods 42 and 43 respectively, saidpiston rods having the up er ends thereof pivotally connected by links44' and'45 to arms 46 fulcrumed upon the upper ends'of posts 47 mountedupon the bed plate 10. {The upper pivoted ends of the links 44 arepivotally.

connected-by pitrnen48. to -levers 4= 9 and 50. These levers' ar'eivotally mou ed, as at 60 in the upper ends of the posts" 1 andsaidlevers are provided with pitmen 61 that are connected to alternatelyarranged crank portions 62'of a shaft 63, journaled in bearings 64,carried bythe girders 4. The shaft 63 alternate with the cylinders 38 intransmitting power to the shaft 63, the cylinders 37 taking air from theauxiliary tank 33 while the cylinders '38 are exhausting and vice versa.This is also true in connection with the cylinders 13 and all of saidcylinders cooperate in transmitting power to the shafts 26 and 63, theshafts operating in unison throughthe medium of the endless sprocketchain 67.

After the main tank 5 has been exhausted, it can be recharged, and thetank is of suiiicient size to permit of the motor being operated for along period of time without recharging, it of course being understoodthat the exhaust .of air from the main tank depends upon the load towhich the machine is subjected.-

When the tank 5 is charged, the tank 33 is also charged in View of thefact that the valve 35 is opened. In some instances but one set ofcylinders is employed to drive both shafts, if so the tank 5 or the tank33 is closed to that set of cylinders which communicate therewith. Whenboth sets of cylinders are used they are open to their tanks for thesupply of air. When the cylinders 37 and 38 are in communication withthe tank 83, the latter is in communication ifoe aaaa with the tank 5but the latter is closed to the cylinders 13 if these are not to beutilized, if utilized they are open to the tank 5. It is of courseunderstood that when the load to which the machine is subjected isgreat, vthen both sets of cylinders are utilized, but when the load islight only one set of cylinders is en'lployed. What I claim -is:

1. In an air motor, the combination of a 'main tank provided with valvedmeans adapted to communicate with a compressed air supply, a pair ofshafts, a drive connection between said shafts, an auxiliary tank havinga valved supply means communicating with said main tank, a pair ofalterinately operating fluid pressure operated devices having valvedconnections with said main tank, a drive connection with one of saidshafts, a pair of alternately operated fluid pressure operating deviceshaving valved supply connections with said auxiliary tank and driveconnections with the other of said shafts, said shafts arranged abovesaid tanks and devices, and support ing means for said shafts.

2. In an air motor, the combination of a main tank provided with valvedmeans for establishing communication with a compressed air supply, apair of shafts and a drive connection between said shafts, an auxiliarytank having a valved supply connection with said main tank, a pair ofalternately operating fluid pressure operated devices having valvedconnections with said main tank and a drive connection with one of saidshafts, a pair of alternately operat-
